Title: Help deleting this CEL 4D0-907-560-AF Post by: amd is the best on December 10, 2013, 07:29:58 PM I have deleted the rear O2's based on what is usually disabled on a B5 M-box (CDKAT/CWDLSAHK) yet I'm still getting this code (attached) for this A8 ECU. Code P1177/17585 is what's coming up. 4D0-907-560-AF
Can someone help me with what address needs to be zeroed? Title: Re: Help deleting this CEL 4D0-907-560-AF Post by: ddillenger on December 10, 2013, 07:38:02 PM Post cat lambda control limit reached brah.
CLRHK brah. Just being humorous. CLRHK=11E2E I guess just set it to 01 and see what happens.

CLRHK=11E2E I guess just set it to 01 and see what happens. Hilarious and helpful! As always, appreciate the help man! I'll give it a whirl. Edit, I already have 11E2E 0'd out. Should it no be 0'd and put it to 1? Title: Re: Help deleting this CEL 4D0-907-560-AF Post by: oldcarguy85 on December 11, 2013, 05:29:03 AM Hilarious and helpful! As always, appreciate the help man! I'll give it a whirl. Edit, I already have 11E2E 0'd out. Should it no be 0'd and put it to 1? What was the original value? The wiki seems to indicate that it needs to be set to an odd number(at least that's my best guess based on the values they suggest). I'd add 1 to the original even number Title: Re: Help deleting this CEL 4D0-907-560-AF Post by: ddillenger on December 11, 2013, 11:37:08 AM CLRSHK

Something seems odd about that. Is the address correct for this ECU?
Title: Re: Help deleting this CEL 4D0-907-560-AF Post by: ddillenger on December 11, 2013, 02:52:32 PM The address is correct, and there is nothing odd about it. The M-box is the odd one with a value of 72.
Set bit 0, or bits 2 and 0. Both will disable trims, setting bit 2 will clear ATV on engine start in addition to trims (Can't hurt, ensures you have no lingering adaptation). 11E2E 0--->5 will prevent the codes.

That is the ONLY change you made between files?
Title: Re: Help deleting this CEL 4D0-907-560-AF Post by: amd is the best on December 14, 2013, 06:00:03 PM that shouldn't be. That is the ONLY change you made between files? That was absolutely the only change. I never did try the 01 value though. Title: Re: Help deleting this CEL 4D0-907-560-AF Post by: ddillenger on December 14, 2013, 06:07:39 PM Odd. Try 01, post results.
Title: Re: Help deleting this CEL 4D0-907-560-AF Post by: amd is the best on February 10, 2014, 05:04:46 PM Results of 01.
Title: Re: Help deleting this CEL 4D0-907-560-AF Post by: ddillenger on February 10, 2014, 05:07:24 PM That is very odd. It's obviously the right address, the bitpairs must have changed. Time for some experimenting man. If you want to bring it out we can strap the emulator in and see what's what.
Title: Re: Help deleting this CEL 4D0-907-560-AF Post by: amd is the best on February 10, 2014, 05:23:56 PM That would be awesome man. Hit me up on Facebook whenever you get a change and we can arrange something. I can deliver the wideband controller too.
Any other guesses for something to try right now? Title: Re: Help deleting this CEL 4D0-907-560-AF Post by: ddillenger on February 10, 2014, 05:40:13 PM Just flip bits and see what's what I guess. That's what I'd do. Maybe phila or prj will chime in.
